Will at CT scan or MRI pick up a parasite?

Will at CT scan or MRI pick up a parasite?

In many instances: Usually we see the results of the body's reaction to the parasite, rather than the parasite itself. Parasites such as cysticercosis can deposit material which en sites the body to react - for instance in the brain. In other situations a byproduct of infection such as an amoebic abscess in the liver can be identified. Virtually every organ system can show the result of parasitic infection. ...Read more

Computed Tomography (Definition)

Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more

Would a CT scan pick up on parasites in brain?

Would a CT scan pick up on parasites in brain?

Parasites: Ct scans detect changes in the brain substance that are produced by a variety of diseases. Sometimes the findings may suggest one illness over another, but they are never specifically diagnostic. Thing like cysticerus, toxoplasmosis, and others are very likely but must be proven by other techniques. ...Read more

Possible for a 6.6mm tumor to not show up on X-ray or CT scan?

Possible for a 6.6mm tumor to not show up on X-ray or CT scan?

A cm is: Roughly a half-inch, so 6.6 is a little more than half that and quite easy to not been seen on ct, and unlikely to be seen on a plain film...And I am speaking of chest. Abdomen or pelvis even easier to miss. ...Read more

Will a brain aneurysm show up on a plain CT scan of the head?

Will a brain aneurysm show up on a plain CT scan of the head?

USUALLY NOT: Since aneurysms are a 'defect' in the arterial system --they can really only be seen with a contrast ct study (angiogram) or a mra (mri-angiogram). One time i did have a patient with a leaking brain aneurysm which the effects of which were barely visible on ct but confirmed on mra--and she made it! ...Read more

Are there things that an MRI head scan can pick up that a CT head scan can't pick up?

Are there things that an MRI head scan can pick up that a CT head scan can't pick up?

Yes: CT is a valuable tool in detecting intracranial abnormalities, and is superior to MRI in depicting some things, but across the board MRI is more sensitive at picking up more abnormalities than CT. ...Read more

Can a CT scan pick up an acoustic neuroma?

Can a CT scan pick up an acoustic neuroma?

Not usually: Ct scans use x-rays and are better for imaging bones than soft tissue. A large acoustic neuroma may be seen on ct scan, but MRI with a contrast medium is able to detect small acoustic neuromas that may only be several millimeters in size. Mri uses a magnet for imaging which also has the benefit of no x-ray exposure. ...Read more

Can a small brain aneurysm show up on a MRI with contrast? (I didn't get an MRA)

Can a small brain aneurysm show up on a MRI with contrast? (I didn't get an MRA)

Yes: Usually CT alone will show brain aneurysm. MRI without contast is added if CT is negative but suspicion is high for aneurysm. Though MRA visualizes blood vessels it is not the diagnostic test of choice for cerebral aneurysm. ...Read more

Would dementia show up on MRI or cat scan?

Would dementia show up on MRI or cat scan?

Not necessarily: Mri and cat scans show anatomical brain changes only, not functional ones. If a dementia is far enough advanced to change brain structures, it would "show up" on these scans. However, there may be a long decline in brain function before that point is reached. There are functional scans which might detect changes before anatomic anomalies can be seen. A normal MRI does not "rule out" dementia. ...Read more

Why would a pancreatic tumor not show up on spiral CT with contrast?

Why would a pancreatic tumor not show up on spiral CT with contrast?

Should show usually: A small lesion in the pancreas might not show up if it did not alter either the contour of the gland or its density. This would be unusual but not impossible. In any event, the "tumor" would have to be very small. Mri might be helpful in such a situation. ...Read more

Will a spect scan pick up Generalized epilepsy?

Will a spect scan pick up Generalized epilepsy?

Might help: A 3-D SPECT scan is the poor man's equivalent of a PET, the former illustrating blood vessel flow patterns, and the latter, metabolic patterns. But we are dealing with anatomical variations secondary to a disorder, and with a paroxysmal process such as epilepsy, we are better off to use EEG monitoring to assess physiology. Can use ambulatory device over 24-48 hrs to seek conclusions. ...Read more

Mri (Definition)

Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists ...Read more

Ct Scan (Definition)

Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more
